The work done in pumping out all the water over the top is approximately 139,064,418.75 ft-lb.

We have,

The volume of the cylindrical tank is given by:

V = πr²h

= π(10 ft)²(30 ft)

= 9,424.78 ft³

Since the tank is half filled with water, the volume of water is:

V_w = (1/2)πr²h

= (1/2)π(10 ft)²(30 ft)

= 4,712.39 ft³

The weight of water in the tank is given by:

W = V_wρg

= (4,712.39 ft³)(62.5 lb/ft³)(32.2 ft/s²)

= 9,270,961.25 lb

To pump out all the water over the top, we need to lift it to a height of 15 feet (since the tank is half filled).

Therefore, the work done in pumping out all the water over the top is given by:

W_work = Wh

= (9,270,961.25 lb)(15 ft)

= 139,064,418.75 ft-lb

Therefore,

The work done in pumping out all the water over the top is approximately 139,064,418.75 ft-lb.

The new function in terms of g(x) is g(x) = -2|x - 3).The correct answer is option B.

To understand why, let's break down the transformation step by step:

1. Translation Down by 3 Units: This means shifting the graph of the function downward by 3 units. To achieve this, we subtract 3 from the original function's expression, resulting in f(x) - 3 = |x| - 3.

2. Vertical Stretch by a Factor of -2: A vertical stretch affects the magnitude of the function's output. When we stretch a function vertically by a factor of a, we multiply the function's expression by that factor.

In this case, the factor is -2. Multiplying the translated function from step 1 by -2, we get -2(|x| - 3), which simplifies to -2|x - 3|.

Therefore, the new function, in terms of g(x), is g(x) = -2|x - 3).

Option B correctly represents this transformation by subtracting 3 inside the absolute value and multiplying the entire expression by -2.Option A does not incorporate the vertical stretch factor of -2, while option C includes an additional unnecessary shift. Option D represents a different linear function, not the translated and stretched absolute value function.

The equation of the parabola is y= 1/255 (x+4)² -8.

Since the parabola opens up, the general equation of the parabola is of the form [tex]$y = a(x-h)^2 + k$[/tex], where the vertex is (h, k).

So, substituting the given vertex (h,k)=(-4,-8), we have y=a(x+4)²-8.

Since the focal diameter is 16, the distance from the vertex to the focus is [tex]$\frac{1}{4}$[/tex] times the length of the focal diameter. Thus, the focus is at a point [tex]$(h,k+p)$[/tex] where [tex]$p = \frac{16}{4} = 4$[/tex]

The equation of the directrix is y = k-p = -8-4 = -12.

Using the formula for the distance between a point (x,y) and the directrix y = k-p, we get:

|y- (k-p)| / √(1+a²)

= |y+ 12|/ (√1+a²)

= |x-h|

Since the focus is on the parabola, the distance from the focus to any point (x,y) on the parabola is given by:

[tex]$$\sqrt{(x-h)^2 + (y-k-p)^2} = |4p(x-h)|$$[/tex]

Substituting the values of (h, k,p), we get:

[tex]$$\sqrt{(x+4)^2 + (y+4)^2} = 16|x+4|$$[/tex]

Squaring both sides and simplifying, we get:

[tex]$$(y+4)^2 = 256(x+4)^2 - (x+4)^2 = 255(x+4)^2$$[/tex]

[tex]$$(y+4)^2 = \frac{1}{255}(x+4)^2$$[/tex]

[tex]$$y+4 = \pm\frac{1}{\sqrt{255}}(x+4)$$[/tex]

Finally, substituting [tex]$y=a(x+4)^2-8$[/tex] and solving for a, we get:

a= (y+8)/ (x+4)²

Substituting this value of a in[tex]$y=a(x+4)^2-8$[/tex], we get:

y= (y+8)/ (x+4)²  (x+4)² -8

Answer:

m∠6 = 50°

Step-by-step explanation:

We know that angles 3 and 6 are same side interior angles.  Whenever a traversal cuts through two parallel lines (AB and CD), the sum of the same side interior angles is always 180.

Thus, we can find the measure of ∠6 by subtracting the measure of ∠3 from 180:

m∠6 + m∠3 = 180°

m∠6 + 130° = 180°

m∠6 = 50°

The length of the rectangle is 4 units.

We have,

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

Let n be the length of the rectangle.

The width of a rectangle is the length minus 2 units.

The width = n - 2

The area of the rectangle is 8 square units.

The area of the rectangle = length x width

8 = n (n-2)

n²-2n - 8 = 0

n²-4n+2n - 8 = 0

n(n-4)+2(n-4) = 0

(n+2)(n-4) = 0

In the uniform distribution, the mean (7.5) is equal to the median (8), making it the data set where the mean is equal to the median.

The data set in which the mean is equal to the median is the uniform distribution. In the provided data set, the bars represent the heights of the distribution. In the uniform distribution, the heights are 8, 6, 6, 8, 7, 8, 6, 8, 8, 8.

To determine the mean and median, we first calculate the mean by summing up all the values and dividing by the total number of values:

(8 + 6 + 6 + 8 + 7 + 8 + 6 + 8 + 8 + 8) / 10 = 75 / 10 = 7.5The mean of the data set is 7.5.

To find the median, we arrange the values in ascending order:

6, 6, 6, 7, 8, 8, 8, 8, 8, 8

Since there are 10 values, the median is the average of the fifth and sixth values, which is (8 + 8) / 2 = 8.

It is worth noting that the other distributions mentioned, namely the normal distribution and the skewed right and left distributions, do not have the mean equal to the median.

The solution to the inequality is x < 3/14.

To solve the inequality -14x > -3 need to isolate the variable x on one side of the inequality sign.

We can start by dividing both sides by -14.

Since we are dividing by a negative number need to flip the inequality sign to maintain the direction of the inequality:

-14x/-14 < -3/-14

x < 3/14

The solution to the inequality is x < 3/14.

The solution by noting that 3 and 14 do not have any common factors so 3/14 is already in its simplest form.

The solution tells us that x is less than 3/14 means any value of x that is less than 3/14 will make the inequality true.

x = 0 x = -1 and x = -0.5 are all values that satisfy the inequality since they are less than 3/14.

We divide both sides of an inequality by a negative number need to flip the direction of the inequality sign.

This is because dividing by a negative number flips the sign of the inequality and we need to maintain the direction of the inequality to ensure that our solution is correct.

Answer:

384.67

Step-by-step explanation:

The margin of error for the 99% confidence interval for the true mean monthly salary of all former students can be calculated using the formula:

Margin of error = z * (standard deviation / sqrt(sample size))

where z is the z-score associated with the desired confidence level (in this case, 99%), standard deviation is the population standard deviation (given as $550), and sqrt(sample size) is the square root of the sample size (15).

The z-score for a 99% confidence level can be found using a standard normal distribution table or calculator, and it is approximately 2.576.

Plugging in the values, we get:

Margin of error = 2.576 * ($550 / sqrt(15))

                ≈ $384.67

Therefore, the margin of error of the 99% confidence interval for the true mean monthly salary of all former students is approximately $384.67.

The high temperatures in City B are more spread out than the high temperatures in City A.

The difference between the means of the two cities is 12 degrees Fahrenheit. This is equivalent to about 4 mean absolute deviations in City A or 5 mean absolute deviations in City B. This means that the high temperatures in City B are more spread out than the high temperatures in City A.

To put it another way, the high temperatures in City A are more likely to be close to the mean, while the high temperatures in City B are more likely to be further away from the mean.

Here is a table summarizing the data:

City Mean high temperature Mean absolute deviation
